22nd March

A day of fewer birds but greater variety, particularly from the sea. The most unusual bird by Portland standards came in the form of a Moorhen that spent the morning calling from Culverwell. However, the days true highlight was a fly-over Serin at the Obs; other land-based migrants included: three SandMartins, 37 Wheatears (the highest count of the spring so far), a lone BlackRedstart, a new RingOuzel at the Obs, a tardy Fieldfare in the top fields, five Blackcaps in the vicinity of the Obs, 75 Chiffchaffs, three WillowWarblers, three Firecrests, 14 Goldcrests, 27 albaWagtails, four Siskins, a Brambling and a new BlueTit (almost as unusual as the Moorhen!). The sea provided some more interest with 56 CommonScoter, three VelvetScoter, four Eiders, three Red-breastedMergansers, 27 BrentGeese, six Red-throatedDivers and a Porpoise.

Elsewhere on Portland there was the loitering pair of Black-neckedGrebes at the Harbour and a single BlackRedstart at Reap Lane.

Although we now know from sound recordings sessions that Moorhens are relatively frequent nocturnal migrants here, daytime sightings aren't even annual and the species is notoriously tricky to see when it does pitch in. Today's bird at Culverwell wasn't even glimpsed despite being audible at close range (in just the sort of spot where you thought you couldn't possibly not have seen it) for extended periods throughout the morning - we even had to go to the lengths of sending a recording to Joe Stockwell and Nick Hopper for them to confirm that it was indeed a Moorhen!

As an aside, Joe mentioned the difference between these calls and those given in flight by nocturnal migrants - we'll have a look at that another day when we've got a bit more time.
